1.5 Glossary of used terms and conceptions
In case of unfamiliar terms in the document, you can find the explanation here.
ALTERNATIVE SOURCE: The heat source is used for systems with solar collectors,
fireplaces and wood stoves when we either do not have a heat source on hand at any
moment or an automatic switch through the signal from the controller of the device (i.e. in
a wood stove) is not possible.
ADDITIONAL SOURCE: The external heat source found alongside the device (i.e.
oil/gas/pellet/external heater furnace) or internal heat source (electrical flow heater) which
is factory integrated in certain types of devices. The spare or additional source can be used
as “assistance” to the device under the so-called bivalent point when the capacity of the
device does not suffice for maintaining the desired temperature. It can be used alongside
the device alternatively (the either-or system) – the switch is automatic.
BACKUP SOURCE: A function, which turns on the selected additional source in the event
of an error or a remote shutdown. The device operates in antifreeze mode. The device will
turn off following the confirmation of an error or interrupt signal from the remote off.
The flow heater which is installed in the device and turns on in the case of device
malfunction (in the so-called antifreeze programme). This ensures temporary operation for
bridging the time until an authorised person from the service company arrives and corrects
the error.
HEATING WATER: The liquid which flows inside the heating system (pipelines, floor, wall
and radiator heating).
DHW: The water intended for sanitary use (cleaning, showering, washing ...).
HEAT PUMP (HP): The device which takes energy from the environment, uses electric
energy to drive the device and releases heat from space heating and DHW. In the text
below the term ‘device’ will be used for the heat pump.
HW: The device takes heat from the earth.
AW: The device takes heat from the air.
WW: The device takes heat from groundwater.
Parameter NORMAL: The desired temperature of heating in the Normal mode of
operation.

2 General facts about the heat pump
2.1 What is a heat pump
A heat pump is a device which uses renewable energy sources (air, earth and water) and enables
us economical and ecologically friendly heating and cooling of the building as well as heating DHW.
Whether it is intended for internal or external installation depends on the device itself. Heat pump
operation:
HEAT SOURCE
HEAT PUMP
HEATING SYSTEM
The device takes heat from the environment or source (groundwater, earth, air) and transfers it to
the water in the heating system. This is achieved with the process of evaporating the coolant in the
evaporator which is a heat exchanger especially designed for this task. This coolant is compressed
in the compressor in the next circuit to a higher pressure which makes the temperature of the
coolant rise to a temperature higher than the temperature of the heated water. This coolant then
condenses in the water-cooled condenser where the heat taken from ground water/earth/air and
electrical energy needed for the operation of the compressor are transmitted to the heating water.
The heating water can be heated up to 65 degrees Celsius and more through this process
(depending on the operating conditions of the device); this makes the devices suitable for
renovating older heating systems.

4 Quick settings
NOTE
The parameters of the TERMOTRONIC controller were set according to project
documentation of the heating/cooling system, recommendations of the manufacturer of
the device and your requests by the authorised contractor for commissions at
commission. At handover, the contractor for commissions is obliged to thoroughly
present you with the possible ways of the device’s operation and explain the setting
modes of the parameters important for the user.
The basic function of the device is space heating and heating the DHW. The controller of the device
calculates the optimal needed temperature of the heating water to achieve the desired air
temperature of the room in dependence on the outside temperature.
Setting the temperature of heating/cooling
The temperature in the heated/cooled room is controlled in two stages, by setting the temperature:
1. of the room with the spatial corrector or thermostat and
2. the heating/cooling water in the accumulator and heating/cooling circuits on the controller
TERMOTRONIC.
NOTE
In case despite the change in the setting of the temperature with the spatial corrector or
thermostat after a longer period of operation of the heating/cooling circuit (in floor
heating this could last up to 4 days) the desired room temperature was not achieved,
check the heating water temperature settings. For settings see chapter 4.2.
4.1.1 Setting room temperature with the spatial corrector KT-2
The spatial corrector KT-2 enables an advanced and very easy settings of room temperature and
basic functions of the device.
By pressing the key or the
display displays the currently set
room temperature. The temperature
is marked by an orange border.
By pressing the key or again
you adjust the desired room
temperature. You confirm the
change by pressing the OK button,

NOTE
The space corrector influences the whole heating circuit and not the temperature of the
individual room. The desired room temperature where the spatial corrector is located
in the reference temperature for all other rooms of the heating circuit controlled by this
spatial corrector.
Before raising the temperature of heated water or the desired room temperature on the
spatial corrector make sure the valves on the heat sources in the room where it is too
cold for you, are completely or sufficiently opened. If the temperature of other rooms is
too high or too low open or close the valves for floor heating or radiators where the
deviations from the desired temperature take place.
NOTE
For maintaining the correct operation of the heating system you have to choose a
suitable operating mode - winter (heating and DHW) or summer (DHW and cooling -
only in certain models). For choosing the mode see chapter4.3.
NOTE
A detailed description of the settings and additional functions (weather report, DHW,
operating mode, information about the state of the device ...) see the manual for the
spatial corrector KT-2.
4.1.2 Setting room temperature with the spatial corrector KT-1
The spatial corrector KT-1 enables basic settings of room temperature.
By pressing the key or the LED display displays the
currently set desired room temperature. By pressing the
key or again you adjust the desired room
temperature. By pressing the keys you adjust the values
by 0.5 °C. The change is confirmed automatically.
Quick setting: By pressing and holding the key the
temperature setting changes in steps of 1 °C.
NOTE
The space corrector influences the whole heating circuit and not the temperature of the
individual room. The desired room temperature where the spatial corrector is located
in the reference temperature for all other rooms of the heating circuit controlled by this
spatial corrector. Before raising the temperature of heated water or the desired room
temperature on the spatial corrector make sure the valves on the heat sources in the
room where it is too cold for you, are completely or sufficiently opened.
If the temperature of other rooms is too high or too low open or close the valves for
floor heating or radiators in the rooms where the deviations from the desired
temperature take place.
NOTE
For maintaining the correct operation of the heating system you have to choose a
suitable operating mode - winter (heating and DHW) or summer (DHW and cooling -
only in certain models). For choosing the mode see chapter4.3.
NOTE
You can find a detailed description of settings and additional functions in the manual
for the spatial corrector KT-1.

4.1.3 Setting the room temperature with a room thermostat
For setting the room temperature with a room thermostat consult the manual which come with the
thermostat or consult the installer.
NOTE
In case the thermostat is turned on all this time and the heating system does not
heat/cool the space to the desired temperature, check the settings of temperatures of
the heating system on the device.
NOTE
For choosing the function of heating or cooling an appropriate thermostat has to be
installed which allows both functions.
NOTE
For maintaining the correct operation of the heating system you have to choose a
suitable operating mode - winter (heating and DHW) or summer (DHW and cooling -
only in certain models). For choosing the mode see chapter 4.4.
4.2 Setting the temperature of heating water
Upon start-up the control of the heating water temperature of your heating system was set to
Heating curve mode which ensures the most energy efficient operation of the device. In case the
automatically calculated temperature of the heating water (in accordance with the external
temperature) is insufficient for ensuring the comfort of living in the rooms, the temperature of the
heated water can quickly be raised or lowered by changing the parameter of cooler/hotter (C/W).
The values of the parameter C/W are adjusted in the menus 1. Circuit 2. Circuit 3. Circuit or
4. Circuit depending on which temperature you want to change. If you want to change (raise/lower)
the temperature of the heated water for the whole building or heating system, change the parameter
C/W in the menu Heating.
NOTE
Upon start-up the heating water temperature control was set to Heating curve mode.
The authorised contractor for commissioning noted your heating water settings of the
heating circuits into chapter 11.
By setting the parameter C/W you set the number of temperature steps (one temperature step
equals 1 °C) for which you want to raise or lower the temperature of heated water. You perform the
settings in the following steps:
1.
Press key (MENU) in the basic menu.
2.
In the user interface, use the key and
choose menu 1. Circuit and press the key
(ENTER).

After conformation the controller calculates the
new temperature setting for the heating circuit
or heated water according to the external
temperature (in case of weather control).
For returning to the basic view press the key
(MENU) twice.
For advanced changing the temperature of the heated water control mode of the heating system
see chapter 5.1.
NOTE
The temperature of heated water can be raised or lowered for no more than
four temperature steps.
The heating and individual circuits settings are separated from the cooling, this
is why all settings for heating remain unchanged with the change of the mode
into cooling. The same is true for parameter settings in the menu Cooling,
1. Circuit, 2. Circuit, 3. Circuit, 4. Circuit and Heating, which are separated
so as to maintain all settings when changing the heating Mode
(winter/summer).
For heating curve you can choose various temperature modes of operation
with setting daily and weekly schedules. See chapter5.4.
NOTE
In case of radiator heating for a significant change, change the parameter C/W for 2 or
3 temperature steps at once but only for 1 temperature step in case of floor heating.
Please note that the responsiveness of the heating system in the case of radiator
heating is quicker than in the case of floor heating. By changing the parameter C/W
several hours can pass (in the case of floor heating) before the heating system
responds properly and you can feel the change of the adjustment.

4.3 Setting the temperature of DHW
Once the temperature of the DHW falls below the set temperature minus the parameter Hysteresis
(example: DHW setting is 50,0 °C, Hysteresis setting is 5,0 °C DHW heating will start at 44,9
°C), the controller switches the device from space heating to heating DHW. Heating DHW has
priority over other modes of operation.
Setting the temperature of DHW is performed in the following steps:
1.
Press key (MENU) in the basic menu.
2.
In the user menu choose the menu DHW with
the key and press the key (ENTER).
3.
In the menu DHW in the first line the parameter
DHW is chosen. To set the parameter press key
(ENTER).
4.
* * appear along the chosen parameter. The
keys and change the value of the
parameter DHW. This raises or lowers the
temperature of DHW.
To confirm the settings press key
(ENTER).
5.
Next to the set parameter you can again find the
symbols > <.
For returning to the basic view press the key
(MENU) twice.
NOTE
The actual reached temperature of heated water in the DHW depends on the adequacy
of the DHW, pipelines, flow and ventilation of the system.
NOTE
For controlling the temperature settings of DHW in the tank you can set different modes
of operation (ECO, Comfort), daily and weekly schedules. See chapter 5.4.

4.4 Changing the operational mode - winter/summer mode
The mode of operation - winter or summer, is chosen according to season. In the time when you
do not need heating or want to cool the rooms, switch to summer operating mode. In case heating
is needed, switch to winter mode. The choice can be automatic or manual.
NOTE
If you do not switch into the summer mode operation in the summer, this can result in
higher energy consumption. The operational costs will be increased for two reasons:
The main circulation pump will switch on from time to time to check whether
the need for heating has arisen.
The additional source could also be turned on (for the protection of the heating
system) if the temperature falls below a certain point, i.e. 12 °C – this depends
on the start-up settings.
NOTE
The cooling function is only provided by reversible and WPG + passive models of the
devices.

device according to
the chosen mode of
operation: Mode

NOTE
In the winter mode (heating and DHW) the heating system works only for heating the
heating water of activated circles and DHW. By using the built-in external switch we
can launch manual switch on/off of the cooling mode of the device.
4.4.1 Changing the operating mode
Changing the operation from winter to summer mode is performed in the following steps:
1.
Press key (MENU) in the basic menu.
